4 Claims.

This invention relates to ventilating devices, and more specifically tonew and useful improvements in a Window air vane device made of Luciteor other plastic material, that can deflect moving air through a windowinto a building.

It is a common experience, particularly with city dwellers, to emergefrom their homes and discover for the first time that a heat wave hasbroken and that the temperature in the streets is considerably lowerthan that in the house. This occurs most frequently when a room orapartment has only one exposure, and the breeze passes by the windowswithout entering them,

It is therefore an object of this invention to provide a device capableof deflecting outside air currents into a room.

Another object is to provide a window air vane device that is easilyinstalled and Operates quietly and automatically.

A further object is to form a device with a resilient control to retaina freely rotating air vane in functioning position.

Still another object is to provide a device that is strong, can be madeand assembled cheaply and is attractive in appearance.

These and other objects are accomplished by forming a window air Vanedevice of a bracket, a vane, means to attach the vane rotatably to thebracket and control means to retain the vane resiliently in functioningposition. In one form of the invention, the attaching means joining thevane and bracket consists of two bearings which permit the vane torotate in relation to the bracket. In the other form the attaching meansconsist of two collars fixed to a vertical bracket rod, and twoeyebolt-shaped elements rotating freely on the rod, and supported by andturning on ball bearings rolling in a race in the collars, the threadedshanks of the eyebolt elements and coacting nuts retaining the vanerotatably on the bracket.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 8 is a detailed sectional view of one of the elements of theattaching means joining the vane and bracket.

Fig. 9 is a detailed sectional view of another of the elements of theattaching means.

In the drawings and in the specification, in which like referencenumbers designate similar parts, a window air vane device In shown inFigs. 1 to 5 inclusive, is comprised of a bracket II, a vane I2,attaching means l3 joining the vane rotatably to the bracket, andcontrol means l4 resiliently holding the vane in functioning positionand limiting its angle of rotation about the bracket.

The bracket I l consists of a tubular arm 15 and a rod [6. The tubulararm 15 has a flange I! at one end and is secured to the window frame byscrews l8 extending through the flange and into the frame. The other endof the tubular arm is bent to form an elbow l9 having internal threads20. The rod I6 has a positioning stop or transverse flange 2|intermediate its ends and external threads 22 on its lower end engagingthe internal threads 20 of the elbow [9 to form an L shaped bracket. Ahexagonal nut 23 threaded on the rod threads 22 locks'the tubular arm 15and rod l6 firmly in position.

The vane l2 consists of a rectangular plate made of a transparent andlight material such as Lucite, and is provided with two holes 24 alignedparallel to the shorter sides of the vane and positioned nearer to ashorter side 25.

The attaching means [3 rotatably joining the vane to the bracketconsists of two bearings 26 (see Fig. 5) and two nuts 21.

Each bearing 26 has a circular head 28 with a hole 29 extendingtherethrough at right angles to its threaded shank 30 which extendsthrough the hole 24 of the vane, and is clamped by one of the nuts 21. Aportion 3| of the head where the shank joins it, is fiat and normal tothe shank axis. The holes 29 of the bearing 26 can admit the bracket rodIS in a sliding fit that permits bracket.

3 the bolt to turn freely on the rod but cannot pass the positioningstop or flange 2| on the rod.

The circular head 28 engages a spherical member 28, snugly fitted on thevertical bracket rod 7 l l, and provides a self centering bearingtherefor;

In assembling the vane and bracket, the bearings 26 are first extendedthrough the holes 24 in the vane until the flat portion 3| of thebearing headis flush with the face-of the vane and the holes 29 arealigned one above the otherl The unthreaded end of the rod I6 is theninserted in the holes of the bearing until the lower bearing restsagainst the stop or flange 2!. The nuts 21 can be threaded on thebearing shanks 30 to lock the vane in position on the bolts, the vaneand bolts being capable of turning freely on the rod 16.

The control means [4- resiliently holding the vane in functioningposition comprises a pair of end aligned chains 32 and 33 having theiradjacent inner ends connected to opposite 'ends of an interposed coilspring 33'. end 34 of the chain 32 is secured to the bottom of the vane12 near its other shorter side 35, and the free end 36 of the chain 33is secured to the tubular bracketarm l5 near its flange H. The spring 3|enables the control to be resilient thus reducing the risk of damage inhighwinds or gales. The length of the control means I-4-can be variedand depends on the size of. the vane, the size of the window, and thepositioning of the window air vane device within the window frame. r 1

By means of this device, abreeze'wh'ich is moving outside a window butdoes not enter it, can turn the vane I 2 until it is held by the controlmeans l4 when the vane will deflect themoving airthrough the openwindow. Since the vane can rotate freely on the rod I6, changes indirection of the breeze will turn the vane automatically topermitmaximum deflection of the air currents into a. room;

In the variation of the invention shown in Figs. 6 to 9 inclusive awindow air vane device 3'! has a. bracket 38 similar to the bracket I 1except that its bracket rod 39 does not have the flange 2| that is onthe bracket rod H5. The device has a vane 40, similar to the vane l2except that holes '4! in the vane 40 are not threaded, and attach-' ingmeans 42 joining the vane rotatably to the The attaching means 42consists of two eyebolt shaped elements 43, two supporting collars 44,ball bearings 45, and two nuts 45. Each eyebolt element 43 has anopening 41 therethrough capable of admitting the rod 39 in a loose fit,a

fiangei48 about the opening, and a threaded shank or pin 49 extending atright angles to the opening 41. The threaded pins 49 fit snugly in'theholes 4! of the vane '40 and are adapted to mate with the nuts 46to'lock the vane to the eyebolts.

, A circular raceway 50 concentric with the openways 50 and 54 areformed and positioned to receive ball bearings 45 to permit freerotational The outer free movements of the eyebolt elements 43 relativeto the collar 44. V A The device '31 is assembled by fitting the 601- 4lars 44 and the eyebolt elements 43 on the rod 39, the collars beingstationary and fixed, and the eyebolts rotating freely thereon and beingspaced so that their pins 49 can be inserted in the vane holes 4!. Thenuts 46 are then threaded on the ins 49 looking them together so thatthe vane 40 can rotate freely about the bracket rod.

As before, a resilient control means 56 limits the angle of rotation ofthe vane and holds it in functioning position resiliently, 1
